Abnormal fibrinolysis in retinal vein occlusion
Australian Journal of Ophthalmology
|August 1, 1981
Summary
Central and branch retinal vein occlusion can stem from abnormal fibrinolytic mechanisms, specifically plasminogen activator enzyme deficiency. This treatable condition may be under-recognized by clinicians.
Area of Science:
- Ophthalmology
- Hematology
- Biochemistry
Background:
- Central and branch retinal vein occlusion (CRVO/BRVO) are significant causes of vision loss.
- Fibrinolytic mechanisms play a crucial role in maintaining vascular patency.
- Previous research has suggested links between thrombotic events and fibrinolytic abnormalities.
Observation:
- A specific abnormality in fibrinolytic mechanisms was identified in patients with CRVO/BRVO.
- This abnormality involves a deficiency in plasminogen activator enzyme activity.
- Seven cases were observed by a single practitioner within a two-year timeframe.
Findings:
- Plasminogen activator enzyme deficiency is a potential underlying cause of certain CRVO/BRVO cases.
- This enzyme deficiency represents a treatable condition.
- The observed frequency suggests potential under-diagnosis in clinical practice.
Implications:
- Diagnosis of plasminogen activator enzyme deficiency could lead to targeted treatments for affected patients.
- Increased awareness among ophthalmologists and hematologists may improve patient outcomes.
- Further research is warranted to elucidate the prevalence and precise mechanisms linking this deficiency to retinal vein occlusions.
